Trivia

Multiplayer

When Anno 1503 was released, there was no multiplayer-mode included - officially... In fact, they placed a file in their /data directory which enables it. The mode was not finished. It lacked a lot of features, balancing and so on. But they wanted to get some feedback from their fans without starting an official beta test. So they hoped a small group of people found out and offered feedback.

Source Code

The Anno 1503 source code is about 400,000 lines long - almost everything coded by just two coders. And the graphician, Ulli Koller, has studied architecture - thus the very detailed buildings.
